Perhaps for multiple unit buildings but I was commenting on the photo and was referring to single unit premises. Let me guess a socket on a light switch is OK down there?
Verizon wanted to use moca exclusively but then a patent dispute arose. Eventually MOCA 2.0 will resolve much of this problem. Ethernet and DSL over phone line is too range bound for high rise buildings. They must use coax or install fiber all the way to each unit for installation of an ONT. Verizon probably underestimated how much money it would cost to wire NYC PROPERLY.. and if they did never had any intention of 100% deployment.
Nevertheless, there is a simple solution for not getting access to do the construction. Skip the building (rather than do a half-ass install) and divert those resources to upgrading outside plant so that customers can get faster speeds (south brooklyn & LI suburbs for example). Cablecos like Cablevision aren't waiting to offer faster speeds and Verizon will be caught behind unable to offer similar speeds with a FTTP solution. Quite a PR problem brewing... could be as big as DSL under the old RBOC days..
The future is voice/internet lines... Video & cable tv are the value added propositions as many people will stream/download video in the future.
